Emerson B-106-300NH Reference Air, Semiautomatic Calibration, Thermocouple, Vee Deflector

Instruction Manual

IB-106-300NH Rev. 4.2 July 2002

Reference Air

World Class 3000

Provides a known oxygen concentration to the reference side of the oxygen sensing cell.

Semiautomatic Calibration

Semiautomatic calibration is performed when the system does not include an MPS 3000 Multi- probe Calibration Gas Sequencer. The IFT 3000 provides prompts to direct the user to switch calibration gases when performing the calibration.

Thermocouple

An electrical device made of two dissimilar metals. A thermocouple develops a millivolt signal proportional to its temperature.

Vee Deflector

Protects the optional ceramic diffusor from the process gases. The vee deflector must be posi- tioned so it points toward the direction of the process gas flow. See Figure 2-2 for an illustration of the vee deflector.
